Design features

SCS technology


  • Highest operational reliability through transmission protocol.
  • Permanent check of radio channels for interfering signals.
  • Automatic blocking of channels by Self Channel Select (SCS).
  • 64 radio channels in protected frequency range, proven worldwide.
  • 433 MHz transmitting frequency – internationally approved and high-penetration.


  • No machine downtime due to interfering signals.
  • High-penetration.
  • Automatic blocking of channels by SCS technology.

Patented thermo-lock® technology


  • Prevents heat transfer from the spindle to the probe.
  • Delivers consistent, precise measurement results even by large temperature differences.
  • HSK shanks with THERMO-LOCK® technology are available in various sizes.


  • Precise measurement results even by large temperature differences.
  • Eliminates uncontrolled expansion of the shank and probe body.

Modular construction

  • Probe RWP38.41 variable, modular extendible.
  • Slim standard extensions can be combined in 3 different lengths.
  • Measuring mechanism near the measuring point for highest precision.
  • For use on machining centres, turning/milling centres and on 5-axis machines with swivelling heads.

Activation / Deactivation

  • Switching on and off via radio-wave transmission.
  • With 3 activation codings available, „A“ / „B“ / „C“, it is possible to operate up to 3 measuring systems, RWP38.41 and RWT35.50 with one receiver.

Trigger force freely adjustable

  • Measuring of thin sections with minimal measuring force.
  • Measuring of soft materials.
  • Measuring with large cross probes at max. measuring force.
  • No false triggering during acceleration.
  • Easy adjustment from the front without dismantling (patented).

Performance and process reliability

  • Protected frequency range, proven worldwide.
  • Safe signal transmission redundant transmission protocol.
  • 64 channels freely adjustable.
  • High transmitting power.

Sturdy and protected

  • Probe housing made of stainless steel.
  • Double sealing of battery compartment.
  • High protection of measuring mechanism with chip protection lid and double, chemical resistant sealing membranes.
  • Measuring mechanism torsion-protected.

Operation suitable for the workshop

  • Easy channel adjustment by push of a button.
  • Digital channel display.
  • Quick battery replacement without tools.
